Roger Vivier Belle De Nuit 100mm in blue patent

Why do I need 3 pairs of Belle de Nuit in different colors?  It's not a question you ask a shoe addict.  I saw them in Shanghai at first and I walked away.  When I saw them again in Hong Kong and the only pair left was in my size I took it as a sign.  You see there are many reasons why a woman must get that pair of shoes.   Love the color and the bronze hardware.  True to size.
